An all-water pit is a pre-treatment structure intended to retain the settling materials present in waste water from a home. Domestic waste water are the water valves (WC, ...) and grey water (room baths, kitchens, laundries). A complete purification system consists of an all-water pit and a treatment system annex (sand lter, spreading network, compact filter ZEOMOP or BIONUT ..).
The pre-filter integrated into the all-water pit is located at the exit.Reliable and secure, it protects against premature clogging of the downstream treatment device (sand filter, network spreading ...) by retaining the un-decanted particles. His manipulation and its maintenance are simple.
To avoid all risks the release of floats during maintenance visits, the system automatically closes the output to the processing device downstream.
